You start 80 miles east of pittsburgh and drive east at a constant speed of 65 miles per hour. (assume that the road is straight and permits you to do this.) find a formula for dd, your distance from pittsburgh, as a function of tt, the number of hours of travel.
To find the distance from Pittsburgh as a function of time, the formula is d = 80 miles + (65 miles/hour × t). The distance increases by 65 miles for each hour of travel.
To find a formula for distance (d) from Pittsburgh as a function of travel time (t), we use the concept that velocity equals distance divided by time (v=d/t). Since you start 80 miles east of Pittsburgh and drive east at a constant speed of 65 miles per hour, your distance from Pittsburgh increases linearly with time. The formula will be:
d = start_distance + (velocity
× time)
d = 80 miles + (65 miles/hour × t)
So, for example, if you drive for 2 hours (t=2), the distance (d) from Pittsburgh will be:
d = 80 miles + (65 miles/hour × 2 hours) = 80 miles + 130 miles = 210 miles

Larry has $20 to spend at the store. He plans to purchase five items that cost $5.79, $7.63, $3.46, $2.99, and $3.65. Larry estimated his total cost to make sure he has enough money for his purchases. Is his estimate accurate? Explain why or why not. $5 + $7 + $3 + $2 + $3 = $20
Answer:
Larry did not round correctly. He used front-end estimation, but he did not round up when appropriate. His estimate will be lower than the amount of money he needs.
Step-by-step explanation:
yeah
Larry's estimation is incorrect.
The total cost of the items that Larry bought will be:
= $5.79 + $7.63 + $3.46 + $2.99 + $3.65
= $23.65
Since Larry estimated his total cost to be $20 while the correct answer is $23.65, then his estimate is wrong.

If the instantaneous velocity of an object is zero, then its acceleration must be:
zero
positive
negative
100 m/s2
not enough information
If the instantaneous velocity of an object is zero, then its acceleration must be zero.
Explanation:If the instantaneous velocity of an object is zero, then its acceleration must be zero. When the velocity is zero, it means the object is not changing its position and therefore not accelerating. So, if the instantaneous velocity is zero, the acceleration is also zero.
Final answer:
An object with an instantaneous velocity of zero could still have positive or negative acceleration, or no acceleration at all. Additional information about the forces acting on the object or its further motion is needed to determine the acceleration.
Explanation:
If the instantaneous velocity of an object is zero, this does not necessarily mean that its acceleration must also be zero. Instantaneous velocity being zero simply indicates that at that particular instant, the object is not moving. However, the object could be accelerating (either positively or negatively), which means it could start moving immediately after. For example, a ball thrown vertically upwards has an instantaneous velocity of zero at the peak of its trajectory, but the acceleration due to gravity is still acting on it, giving it a negative acceleration. Acceleration can also be positive if the object starts to move from a state of rest due to a force. Therefore, with only the information that instantaneous velocity is zero, we cannot determine the acceleration without additional context about the forces acting on the object or its subsequent motion.
The correct answer to the question is: not enough information.

Answer:
Harry's weight fluctuated significantly within minutes, indicating a potential issue with the scale's accuracy or calibration. He should address the problem to ensure reliable weight measurements.
Explanation:
It seems like there might be a problem with the scale's accuracy or consistency. Harry's weight fluctuated significantly within just a few minutes, which is highly unlikely under normal circumstances. Such drastic changes in weight in such a short amount of time are not physically possible, indicating a potential issue with the scale's functionality or calibration. It's possible that the scale is malfunctioning, providing inaccurate readings, or there may be external factors affecting the measurements, such as an unstable surface or improper usage of the scale. It's important for Harry to address this issue with the scale and possibly seek assistance from a professional to ensure accurate and reliable weight measurements.

Felicity put down 800 on a used car. She took out a loan to pay off the balance of the cost of the car. Her monthly payment will be 175. After 9 months how much will she have paid for the car?
After 9 months, the amount she has paid for the car is 2375.
Given,
Felicity put down 800 on a used car.
She took out a loan to pay off the balance of the cost of the car.
Monthly payment = 175.
We need to find the amount paid for the car after 9 months.
What is a down payment?It is a sum of money that a buyer pays in the early stages of purchasing a good.
We have,
Down payment = 800
Monthly pay = 175
So we can write it as,
1 month = 175
Multiply 9 on both sides.
We get,
9 x 1 month = 9 x 175
9 months = 1575
The total amount she has paid after 9 months is :
= Down payment + 9 months payment
= 800 + 1575
= 2375.
Thus after 9 months, the amount she has paid for the car is 2375.

Does there exist a function that is not a relation
Every function is a kind of relation by definition. A function is a relation where every input is paired with exactly one output. Therefore, there doesn't exist a function that isn't a relation.
Explanation:In mathematics, every function is a relation, but not every relation is a function. A function is a special type of relation where every input (or x-value) is paired with exactly one output (or y-value). This is often referred to as the vertical line test. If any vertical line intersect the graph of the relation at more than one point, then it is not a function. Therefore, there does not exist a function that is not a relation, because by definition, a function is always a relation.

Identify the transformation that maps the figure onto itself.
Answer:
The correct option is C.
Step-by-step explanation:
From the given figure it is clear that the vertices of the parallelogram are (0,0), (0,-6), (4,-8) and (4,-2).
If a figure rotated 180° about (a,b), then
[tex](x,y)\rightarrow (2a-x,2b-y)[/tex]
If the figure rotated 180° about (2,-4), then
[tex](x,y)\rightarrow (2(2)-x,2(-4)-y)[/tex]
[tex](x,y)\rightarrow (4-x,-8-y)[/tex]
So, the vertices of image after rotated 180° about (2,-4) are
[tex](0,0)\rightarrow (4,-8)[/tex]
[tex](0,-6)\rightarrow (4,-2)[/tex]
[tex](4,-8)\rightarrow (0,0)[/tex]
[tex](4,-2)\rightarrow (0,-6)[/tex]
The vertices of image are same as vertices of preimage. So, 180° rotation about (2,-4) maps the figure onto itself.
Therefore the correct option is C.
(01.05) what is the slope-intercept form equation of the line that passes through (3, 4) and (5, 16)? (1 point) y = 6x − 14 y = −6x + 14 y = −6x − 14 y = 6x + 14
Answer:
The answer is [tex]y=6x-14[/tex]
Step-by-step explanation:
In order to determine the slope-intercept form equation, we need to know the formula. The formula needs a slope (m) and a point (x,y) that belongs to the equation.
[tex]y-y_1=m(x-x_1)\\m=slope\\(x_1,y_1)=point[/tex]
For m:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
So, first we have to define every variable and then we replace them into the formula:
[tex]P_1=(3,4)\\P_2=(5,16)\\m=\frac{16-4}{5-3}\\m=\frac{12}{2}=6[/tex]
It doesn't matter the order of how you define the points. The result will be the same.
Then:
[tex]y-4=6*(x-3)\\y=6*(x-3)+4\\y=6x-18+4\\y=6x-14[/tex]
Finally, the slope-intercept form equation is [tex]y=6x-14[/tex]
